  • The present study was performed to establish the cephalometric norms and to study characteristics of craniofacial skeleton of Korean male and female with normal occlusion. The author studied and analyzed statistically vertical cephalometric measurements of the 52 adult male ranging in age from 18 to 26 years and 43 adult female ranging in age from 16 to 30 years with normal occlusion and acceptable profile. The results were as follows; 1. Cephalometric craniofacial norms and standard deviation chart were abtained about adult Korean male and female with normal occlusion. 2. Vertical dimensions of the craniofacial skeleton were larger in male than in female. 3. Lower face was more divergent in female than in male. 4. In simple correlation coefficients between vertical linear mesurements in male and female, high correlation were shown between ATFH and ALFH, PTFH and PLFH, ALFH and ALDH, PLFH and PLDH.

  • 134 Dutch cone (mechanical cone) and 9 piezocone (electronic cone) penetration tests have been performed in the southwestern part of Korea. In general, Dutch cone results may be different from that of piezocone due to the difference in structure of the cones. 6 Dutch cone and piezocone test data which were obtained at the same point respectively, were analyzed and plotted in soil classification chart proposed by Robertson et. al.(1986, 1990). Cone factors of Dutch cone and piezocone test empirically have been determined using laboratory and field vane test results. Using this cone factors, it was shown that there was good correlation between shear strength estimated using cone resistance and that of laboratory test and field vane tests. It was found that there was a good correlation between cone resistance from Dutch cone and that from piezocone. Relationship formula was also suggested. Dutch cone test provides a useful means for stratigraphic profiling in large project and has some advantage over piezocone in particular situations, such as very soft clay ground and dredged area.

  • Purpose: The osmolar gap increases in proportion to the ethanol level. Some previous studies have shown that the correlation between the osmolar gap and the ethanol level is weak in trauma patient by using an indirect comparison with other patients. We conducted a direct comparison of the correlation of the osmolar gap to the ethanol level between trauma patients and non-trauma patients. We also analyzed the accuracy of the estimated ethanol level between the two groups. Methods: The research candidates were adult patients who had visited the emergency department of our hospital from December 2003 to November 2008. By using a retrospective chart review, we classified them into three subgroups: non-trauma without shock, trauma without shock, and trauma with shock. In each group, we compared the correlation between the osmolar gap and the measured ethanol level, and we analyzed the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient. Results: Four hundred forty-seven patients were enrolled in this study. For correlation of the osmolar gap and the measured ethanol level, Pearson's correlation coefficient was 0.916 in all patients, 0.939 in non-trauma without shock patients, 0.917 in trauma without shock patients, and 0.844 in trauma with shock patients. In the analysis of the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient, the accuracy in trauma with shock patients was lower than that in non-trauma without shock patients. Conclusion: We found that the correlation between the osmolar gap and the measured ethanol level in the patient group with trauma was lower than it was in the patient group without trauma. Moreover trauma patients with shock had a lower accuracy of the estimated ethanol level than non-trauma patients.

  • The new definition of calibration coefficients is proposed for a five-hole Pitot tube. Two-angle chart calibration other than one-angle variation is considered to improve the accuracy in the measurement of the three-dimensional velocity fields. Several sets of correlation coefficients are introduced for different shapes of the probe tip. The calibration method with one-angle variation is compared with the new two-angle chart calibration method and the improvement of the present method is clearly shown.

  • Objectives : This study was aimed to evaluate the correlation between changes in disease severity and serum total IgE or eosinophil count in individual patients of atopic dermatitis depending on the change of severity. Methods : We performed a retrospective chart review of 8 cases of atopic dermatitis who underwent blood tests more than five times. Disease severity was assessed by objective SCORing of Atopic Dermatitis index (OSI). Blood tests include serum total IgE, eosinophil counts, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCr). In each subject, on the day that the blood test was performed, OSI was also assesed by a same physician. Correlation between OSI and total IgE or eosinophil count was analysed by nonparametric correlation analysis. Results : There was a statistically significant positive correlation between OSI and total IgE in three cases and a positive correlation between OSI and eosinophil count in two cases. In other three cases, there were no significant correlation. There were no cases that OSI correlated with total IgE and eosinophil count at the same time. In all cases, AST, ALT, BUN and SCr were stable. Conclusions : We suggest that total IgE and eosinophil count may reflect the severity of atopic dermatitis differently in individual patients. We also suggest that total IgE and eosinophil counts may be used as biomarkers to predict the severity of atopic dermatitis in some patients depending on the underlying pathology.

  • This study investigated garment formability of the 73 breathable fabrics for sports-wear garment and their fabric mechanical properties were measured using KES-FB and FAST systems. Predicted garment formability from the mechanical properties measured using KES-FB and FAST systems was compared and discussed with fabric structural parameters. In addition, virtual 3D simulation silhouette by I-designer CAD system wear appearance by simulation using 3D CAD system. And compared with FAST finger chart by mechanical properties of FAST system. The correlation coefficients of extensibility and shear modulus between KES-FB and FAST systems were high, however, bending rigidity and compressibility showed relatively low correlation coefficients. The correlation coefficient of garment formability of breathable fabrics between KES-FB and FAST systems was 0.82. It revealed that garment formability can be predicted from fabric mechanical properties by KES-FB and FAST systems. The garment formability of nylon breathable fabric was higher than that of PET one, and the garment formability of laminated breathable fabric showed the highest value compared to coated, dot and hot melt laminated breathable fabrics. It revealed that garment formability of breathable fabrics for sports-wear can be predicted from fabric mechanical properties and garment formability was dependent on the materials, finishing method and fabric structural parameters.

  • Nile perch and Nile tilapia are major commercial species in Uganda, and thus require continuous production. However, their production is impacted by anthropogenic activities such as fishing in breeding habitats. The aim of this study was to identify and characterize Nile perch and Nile tilapia fish breeding habitats on Lake Kyoga. Water quality, lake bottom, fish and vegetation type samples were collected from 20 sites in April of 2021 and 2022. Key informant interviews were conducted with experienced fishermen at five fish landing sites. The water quality parameters indicated significant difference within the sites using analysis of variance. Sandy and muddy bottom types were equally spread at 40% each by use of a pie chart. Fish gonads showed no significant difference among the 20 sites. Bivariate correlation analysis of the vegetation types indicated a strong negative correlation with Nile perch while Nile tilapia had a positive correlation. Principal component analysis of the water quality, fish gonads and habitat vegetation components cumulatively contributed 82.5% in characterizing a fish breeding habitat. Four sites for Nile perch and four sites for Nile tilapia were characterized as breeding sites on Lake Kyoga and are recommended for mapping and gazettement as breeding habitats for sustainable fisheries management.

  • The purpose of this study was to examine the correlation between self-efficacy and self-care of hemodialysis patients. The subjects consisted of 140 hemodialysis patients who underwent hemodialysis at 2 university hospitals. The data were collected by questionnaires and chart review. The questinnaire used the self-efficacy tool developed by Kim Ju Hyune(1995) and the self-care tool developed by literature review and indepth open openended questions to 10 patients. Also, the questionnaire included physiologic data which collected through review of the patients' charts. The statistical analysis was used the SPSS program for frequency, mean, t-test, ANOVA and Pearson correlation. The results were as follows : 1. The mean score for general self-efficacy of hemodialysis patients was 3.103(1-4point) and there were significant differences according to percieved health. The mean score for specific self-efficacy of hemodialysis patients was 3.113 (1-4point) and there were significant differencies according to percieved health, side effects and complications which related hemodialysis. 2. The mean score for self-care of hemodialysis patients was 3.822(1-5point) and there were significant differencies according to marital status and economic level. 3. The relationship between general self-efficacy and self-care was a positive correlation(P=.000). The relationship between specific self-efficacy and self-care was a positive correlation(P=.000). In conclusion, this study revealed the level of self-efficacy and self-care, and the positive correlation between self-efficacy and self-care in hemodialysis patients. Therefore, intervention is needed to promote self-efficacy for self-care of hemodialysis patients. Considering the vulnerable self-care area same as checking blood pressure and weight, fluid restriction, social adjustment, exercise and rest, luther studies should develop self-efficacy promoting programs for self-care of hemodialysis patients.

  • Extraction conditions, spectrometric, and sensory properties of pigment extracts from green discolored garlic (GDG) were studied for development of green index to evaluate degree of green discoloration of garlic. GDG pigments were extracted using polar solvents, such as methanol, ethanol, and water. Methanol with 1% HCl resulted in highest extraction of green pigments. Extraction of pigments was affected by temperature, and extracted pigments were partially destroyed at high temperatures. Optimum conditions for extraction of green pigments were $20^{\circ}C$ for 30 min. Because green pigments are unstable at room temperature, and no method has been reported to evaluate degree of green discoloration of garlic, color chart was designed by mixing varying amounts of control and GDG. High correlation was observed between sensory scores and "a" value of color chart samples (y=-3.465x - 11.676) with $R^2$ of 0.993. Green index (GI) was developed based on linear regression equation between sensory scores and "a" values. Sensory panel recognized green discoloration of garlic at $GI{\geq}3.0$. GI developed in this study could be utilized to evaluate degree of green discoloration of garlic during cold storage and distribution of garlic.
